Subject: Unit converters

A centimeter measurement often comes from a tape used for furniture, clothing or body height. Keep the full reading, including a decimal part, when comparing it with a specification written in another unit. A decimal length is different from a feet-and-inches notation.

One centimetre is exactly 0.01 meters, so 175 cm is 1.75 m. To convert cm to meters, multiply by 0.01; to convert back, multiply by 100.

The centimetre is one hundredth of a metre, the SI base unit of length. Because both units are defined exactly, the factor above is exact and the results here carry no conversion error.

## Inputs

- **Centimeters (cm)**

## Results

- Meters (m) — main result
- Conversion
- 1 m in centimeters (cm)

## Formula

$$
\text{meters} = \text{centimeters} \times 0.01
$$

## Worked examples

### 175 cm to m

- Centimeters (cm): 175 cm
- **Meters: 1.75 m**
- Checked against: Exact-fraction computation from the legal unit definitions (scripts/gen-pairs.py, Python fractions)

### 50 cm to m

- Centimeters (cm): 50 cm
- **Meters: 0.5 m**
- Checked against: Exact-fraction computation from the legal unit definitions (scripts/gen-pairs.py, Python fractions)

### 500 cm to m

- Centimeters (cm): 500 cm
- **Meters: 5 m**
- Checked against: Exact-fraction computation from the legal unit definitions (scripts/gen-pairs.py, Python fractions)

## Questions

### How should I enter 175 centimeters in a meter field?

Enter 1.75 m, found by dividing 175 by 100. This is useful when a form expects decimal meters. Keep the decimal point; entering 175 in that field would describe a length one hundred times larger.

### How many meters are in a centimetre?

One centimetre is exactly 0.01 meters. The centimetre is one hundredth of a metre, the SI base unit of length.

### How do you convert cm to meters?

Multiply the number of centimeters by 0.01. For example, 175 cm × 0.01 = 1.75 m. To go the other way, divide by 0.01.

### How accurate is the centimeters to meters converter?

Accuracy depends on your inputs and the method's assumptions. Decimal arithmetic uses 50 significant digits, but estimates, numerical methods and source data can be less precise; the displayed rounding does not remove those limits. It is checked against 3 worked examples whose answers come from independent sources; for example, “175 cm to m” is checked against Exact-fraction computation from the legal unit definitions (scripts/gen-pairs.py, Python fractions).
